  • Biofouling Control In Cooling Towers With A Halogen Stabilizer
    10/22/2020

    Biofouling in cooling towers is undesirable because it can reduce heat transfer efficiency, restrict water flow, and accelerate corrosion rates. Of even greater concern is the fact that pathogen growth in cooling towers can lead to disease transmission. Given the favorable growth environment of a cooling tower, these microorganisms can reproduce, proliferate and form complex biofilm communities. Legionella bacteria, which cause Legionnaires’ disease, are one of the greatest concerns from a public health standpoint because infections are often lethal and cooling towers are the most frequently reported non-potable water source of Legionnaires’ disease outbreaks (Llewellyn 2017).

DRINKING WATER PRODUCTS

Harmsco has developed a higher capacity filter housing that is BABA compliant, and it is available in a 3X, as well as a 5X model.

The WATERFLUX ,3300 is an electromagnetic flowmeter (EMF) for demanding water applications and custody transfer operations (MID MI-001, OIML R49; MI-004). The high-end meter is particularly suitable for applications requiring high accuracy and extensive diagnostics. With its rectangular and reduced cross-section the EMF enables a stable measurement even at low flow rates. This way, the WATERFLUX ,3300 offers a much larger turndown ratio (1000:1) than mechanical flowmeters (e.g. turbine meters) in drinking water distribution networks.

CHEM-FEED® Engineered Skid Systems were designed and engineered using solid modeling tools for superior piping installation and easy component maintenance. Custom-engineered universal mounting blocks provide for easy component servicing and replacement.

Meeting the demand for clean water has never been more challenging. Communities around the world are facing a growing water stress – an insufficient supply, in terms of water quality or water quantity – and often both. Many are turning to potable reuse and drinking water remediation to meet these demands. The TrojanUVFlex®AOP can be part of the solution. This UV advanced oxidation system destroys a range of chemical contaminants while simultaneously providing final treatment, helping municipalities relying on lower quality water sources to continue producing high-quality potable drinking water.

HYMAX GRIP  joins and restrains a wide selection of pipes of different types and diameters, easily and reliably. Due to its patented design, it allows the joining of pipes of the same or different materials and diameters and prevents axial pipe movement.

During a trip to Africa in 2006, Damon made it his mission to help people in developing countries have access to safe water and sanitation. He talks to Katie Couric in "World 3.0".

Water infrastructure projects often face extreme installation conditions, from deep-trench burials to exposed bridge crossings. Ensuring long-term reliability requires a material capable of withstanding environmental stressors that can compromise other piping options. Ductile iron pipe offers superior durability, maintaining its structural integrity regardless of temperature fluctuations or UV exposure. Watch the full video to explore these benefits in action.

ABOUT DRINKING WATER

In most developed countries, drinking water is regulated to ensure that it meets drinking water quality standards. In the U.S., the Environmental Protection Agency (EPA) administers these standards under the Safe Drinking Water Act (SDWA)

Drinking water considerations can be divided into three core areas of concern:

  1. Source water for a community’s drinking water supply
  2. Drinking water treatment of source water
  3. Distribution of treated drinking water to consumers

Drinking Water Sources

Source water access is imperative to human survival. Sources may include groundwater from aquifers, surface water from rivers and streams and seawater through a desalination process. Direct or indirect water reuse is also growing in popularity in communities with limited access to sources of traditional surface or groundwater. 

Source water scarcity is a growing concern as populations grow and move to warmer, less aqueous climates; climatic changes take place and industrial and agricultural processes compete with the public’s need for water. The scarcity of water supply and water conservation are major focuses of the American Water Works Association.

Drinking Water Treatment

Drinking Water Treatment involves the removal of pathogens and other contaminants from source water in order to make it safe for humans to consume. Treatment of public drinking water is mandated by the Environmental Protection Agency (EPA) in the U.S. Common examples of contaminants that need to be treated and removed from water before it is considered potable are microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals and radionuclides.

There are a variety of technologies and processes that can be used for contaminant removal and the removal of pathogens to decontaminate or treat water in a drinking water treatment plant before the clean water is pumped into the water distribution system for consumption.

The first stage in treating drinking water is often called pretreatment and involves screens to remove large debris and objects from the water supply. Aeration can also be used in the pretreatment phase. By mixing air and water, unwanted gases and minerals are removed and the water improves in color, taste and odor.

The second stage in the drinking water treatment process involves coagulation and flocculation. A coagulating agent is added to the water which causes suspended particles to stick together into clumps of material called floc. In sedimentation basins, the heavier floc separates from the water supply and sinks to form sludge, allowing the less turbid water to continue through the process.

During the filtration stage, smaller particles not removed by flocculation are removed from the treated water by running the water through a series of filters. Filter media can include sand, granulated carbon or manufactured membranes. Filtration using reverse osmosis membranes is a critical component of removing salt particles where desalination is being used to treat brackish water or seawater into drinking water.

Following filtration, the water is disinfected to kill or disable any microbes or viruses that could make the consumer sick. The most traditional disinfection method for treating drinking water uses chlorine or chloramines. However, new drinking water disinfection methods are constantly coming to market. Two disinfection methods that have been gaining traction use ozone and ultra-violet (UV) light to disinfect the water supply.

Drinking Water Distribution

Drinking water distribution involves the management of flow of the treated water to the consumer. By some estimates, up to 30% of treated water fails to reach the consumer. This water, often called non-revenue water, escapes from the distribution system through leaks in pipelines and joints, and in extreme cases through water main breaks.

A public water authority manages drinking water distribution through a network of pipes, pumps and valves and monitors that flow using flow, level and pressure measurement sensors and equipment.

Water meters and metering systems such as automatic meter reading (AMR) and advanced metering infrastructure (AMI) allows a water utility to assess a consumer’s water use and charge them for the correct amount of water they have consumed.
